Effect of LIF (or IF) neurons and the leak factorSNN鲁棒性的另一个主要影响因素是其高度非线性的神经元激活(IF或LIF),而ANN主要使用像ReLU这样的分段线性激活。为了解释这种非线性的影响,我们进行了概念实验证明。我们给一个ReLU和一个LIF神经元(等式3中的λ=0.99)输入一个干净输入和相应的对抗输入。两个输...
LIF neurons work in an event-driven manner such that higher performance can be achieved with less power. The goal of this work is to integrate ViT and LIF neurons to build and train an end-to-end hybrid network architecture, spiking vision transformer (S-ViT), for the cla...
In this novel research, we have modelled a supervised Spiking Neural Network algorithm using Leaky Integrate and Fire (LIF), Izhikevich and rectified linear neurons and tested its spike latency under different conditions. Furthermore, these SNN models are tested on the MNIST dataset to classify the...
(LIF) neurons. Results are presented on Fig.3. We set the dimension of the network to fit a region of 447 × 447 pixels, the network then using 999045 neurons. This amount is compatible with existing neuromorphic hardware implementation on the TrueNorth platform (1 million neuron27) or...
In biological neural systems, different neurons are capable of self-organizing to form different neural circuits for achieving a variety of cognitive functions. However, the current design paradigm of spiking neural networks is based on structures derived from deep learning. Such structures are dominated...
Hierarchical feature discovery using non-spiking convolutional neural networks (CNNs) has attracted much recent interest in machine learning and computer vision. However, it is still not well understood how to create a biologically plausible network of brain-like, spiking neurons with multi-layer, uns...
RSNNs consisting only of LIF neurons do not even reach good performance on TIMIT with BPTT3. Hence, we are considering here LSNNs, where a random subset of the neurons is a variation of the LIF model with firing rate adaptation (adaptive LIF (ALIF) neurons), see Methods. The name LSNN ...
LIF neurons have been realized in analog electronics24,25, in digital electronics with event-driven processors26,27, and in photonics with optical nonlinear materials28. A simple method for building a digital event-driven system with delay in a FPGA or application-specific integrated circuit (ASIC...
